JOHN GREEN. OF ST. LOUIS, MISSOURI. ASSIGNOR TO J. S. ANDREWS & COMPANY, OF NEW YORK, N. Y., A CORPORATION OF NEW YORK.

CAR-TRUCK.

Specification of Letters Patent.

Patented Dec. 11, 1906.

To alt w/wm, [I may concern.-

Be it known that 1, JOHN GREEN, a citizen 5 of the United States, and a resident of the city of St. Louis and State of Missouri, have invented a new and useful Improvement in Oar lrucks, of which the following is a specification.

My invention relates to car-trucks, and has for its principal object to improve the means for hanging the brake.

. It consist-s in the parts and in the arrange ments and combinations of parts hereinafter described and claimed. r

In the accompanying drawings, which form part of this specification, and wherein a like symbols refer to like parts wherever they occur, Figure 1 is a view of a side frame embodying my invention, partly in elevation and partly in longitudinal vertical section. Fig. 2 is a vertical cross-section on the line 2 2 of Fig. 1 of a truck side frame embodying my invention with the brake-hanger shown in position. Fig. 3 is a cross-sectional detail of the brake-hanger hook, showing its relation to the side frame prior to being upset therein, and Fig. 4 is a detail end view of the boss in which the brake-hanger hook is mounted.

In ordinary car-building practice the distance' from the side frame to the point where the brakes are hung is approximately nine Heretofore cast-steel side frames have been formed with the brake-hanger hook integral therewith; but on account of the necessary length of such hook it was liable to be cast defectively and was also liable to break off in practice, in which case the whole side frame had to be discarded.

In the present invention the side frame 1, which may be of any suitable construction, has bosses 2 formed on its outerface, and through these bosses extend horizontal holes. The body portion of the holes is preferabl circular, while the outer portion thereoft at is, the portion in the bossesflares outwardly and is of polygonal section. Mounted in each of the holes on the side frame is a brake-hanger hook. The brakehanger hook comprises a body portion 3 of proper size and length to extend through the side frame.

hole in which it is" mounted and a portion 4, which projects inwardly from the side frame and terminates in an upwardly-extending hook 5. This brake-hanger hook is provided with a shoulder 6, adapted to abut against the inner face of the side frame. The outer' end of the brake-hanger hook is of proper length to project outwardly beyond the boss 011 the outer face of the side frame. In practicethe body portion 3 of the brakehanger hook is heated and then set into the hole in the side of the frame from the inner side and properly positioned. While its proj ecting end portion is still hot, it is swaged or upset against the flaring pyramidal inner wallv of the boss, whereby it is firmly locked against rotation, as well as against all other motions relative to the side frame. I

The advantages of'the foregoing construction are obvious. In the first place it eliminates one of the difliculties of casting the It permits the brakc-hanger hook to be made of the shape and material most suitable for its purpose for instance, wrought-steel--whoreas heretofore said hook has been made of cast-steel and its form has been limited by the requirements under which it was produced. In case of breakage the hanger-hook can be cut out from the side frame and replaced with another brakehanger hook without having to discard the sido frame or even to remove it from the truck.

Obviously my device admits of considerable modification within the scope of my invention, and therefore 1 do not wish to be limited to the specific construction shown and described.

What I claim is .1. A car-truck comprising a side frame having a horizontal hole therein and a brakehanger hook mounted in said hole.

2. A car-truck comprising a side framc having an outwardly-flaring horizontal hole therein and a brakehanger mounted in said holo.

3. A car-truck comprising a side'frame having a horizontal hole whose outer portion flares pyramidally and a brake-hanger hook comprising a body portion upset in said pyramidal portion and la. :hoo'k portion projectportipn of ahele and an upturned portion ing from the inner face of said side frame. prqecting from the inner face of said frame.
